Calathea

Calathea leaves are used in the tropics (mostly Brazil) for handicraft and food wrapping. Because of the diversity of the leaf shapes, baskets are weaved with the lanceolate leaves, and food is wrapped with the wider leaves. The colorful leaf markings of most Calatheas make them economically important as houseplants, and their popularity has been growing. The Calathea veitchiana ‘Medallion’ (Medallion calathea), Calathea lancifolia (Rattlesnake calathea), and the Calathea ornata (Pinstripe calathea), are some of the most popular species.
